What are Python variables. By definition, a variable is something that may change often in your program. First, you use variables to refer to various kinds of data such string, integer, list, etc. Then you manipulate this data through variables.
Cysts are non- cancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. They can appear anywhere and feel like small peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
I can only give you the definition of anechoic cysts. It means that the cyst absorbs the sound waves of the ultrasound and doesnt bounce them back. I dont know if that indicates a fluid filled cyst. (A simple cyst would be good if you have a cyst.) A cyst is a closed pocket or pouch of tissue.
